My invention is more particularly designed for reducing to a homogeneouspulp.or batter the familiar sour curds or coagulated milk, known in somedistricts of the United States as schmier -kase. Machines heretoforedevised for that purpose have failed of general adoption,in consequence,it is believed, of lack of precaution against the tendency seen incurds, in common with other unhomogeneous semi-liquids, for the moremobile or watery portions to escape down the central passage, leavingthe thicker ingredients to accumulate upon its walls. This action in thecase of curds has been especially objectionable, partly by the unduepreponderance of whey in the product, rendering it unfit for market, butstill more seriously by the contamination due to destructivefermentation of the arrested portions. Still another important objectionhas consisted in the inoperativeness of the apparatus arising from themore orless complete closure of the passage, except along the restrictedcentral channel kept open by the downrush of the more watery portions. Afurther defect of the expedients which, so far as known to me, haveheretofore been attempted has been the failure of the mere rollingormashing actions employed to secure proper disintegration of thecaseine and its incorporation with the whey.

The machine devised by me compels passage of the entire material downthe sides of the passage, and while so passing subjects it to a rubbingor triturating rather than to a mere mashing action.

In the accompanying drawings, Figure l is a vertical section in theplane of rotation of the trituratingrollers of a machine embodying myinvention. Fig. 2 is a top view of the machine. Fig 3 is a sectionalrepresentation of the feeding-hopper detached.

A is an open frame, of suflicient height for convenient reception of areceptacle, B, and for support at the proper elevation of thedegranulating mechanism proper, in which two identical cylinders, C G,of cast-iron, are so and outward toward brakes E E, attached to thesides of the feeding-hopper F, which hopper has battens f, by which itrests upon the frame in the manner shown.

The brakes E E consist of strips of stout plate-iron or plate-steel,bent in the manner shown, and held in place by buttons J J and cleats KK, and adjusted to the desired proximity to the cylinders by means ofwedges E. Slots f in the hopper ends enable said hopper to receive theshafts of the triturating-cylinders, while hooks L L, that depend fromthe supporting-battens f, and that engage in staples M M, hold thehopper to its place upon the frame.

To prevent seepage of material between the cylinder ends and thehopper-walls, I attach to the latter linings N, whose lower edges areformed, as shown, to fit the peripheries of the cylinders. Rotation ofthe cylinders is secured by a driving-pulley, G, upon the shaft of oneof them, that takes a belt, H, from a steam-engine or other motor, andthis cylinder has a spur-wheel, I, that gears into an identical wheel,1, upon the other cylinder.

The metallic surfaces that are exposed to contact with the material arepreferably protected against oxidation-as, for example, by enameling ofthe cylinders and by tinning or zinc-plating of the brakes.

The operation is as follows: A suitable receptacle, B, being providedunder the place of discharge, the hopper is supplied with material. Thecylinders being then rotated, as indioated by the arrows, the materialis conveyed by their peripheries from the central parts of the hopperconstantly outward against the brakes E E, and, on its way out,undergoes, between the peripheries of the cylinders and the concavefaces of the brakes, a pro longed rubbing or triturating action, quiteequal in result to and incomparably more expeditious than that of thebraiding-paddle ordinarily employed.

The described movement of material from the center toward thehopper-walls prevents accumulations thereon, and makes the apparatusself-scouring.

The hereinexplained mole of attachment of the brakes and cleats to thehopper, and of the latter to the frame, permits ready removal andseparation of these members for cleansing or other purposes.

The above-described embodiment of my invention is susceptible of variousmodifications. For example, a handle on one of the cylinder-shafts mayenable the machine to be driven by hand instead of by power, andsetscrews may be substituted for wedges for setting up the brakes.

I claim herein as new and of my inventi0n- 1. In acurd-degranulator, thecombination, with the brakes E E at the hopper sides, of
